Braidability and Formability for 3D Braided Structural Shapes

摘要

This final report outlines the research results obtained under the AFOSR Grant F49620-97-1-0160 for the period from 1 March 1977 to 31 December 1999. The research was partially augmented by the AASET Grant F49620-96-1-0283 for the period from 1 July 1997 to 31 December 1999. The main objective of the research was to develop a rational design/analysis methodology for a class of 3D braided structural shapes for aerospace applications. Research was carried out with two concurrent programs - the experimental program and the simulation program - involving design, braiding of performs, consolidation and shape forming, fiber architecture determination and description, mechanics modeling, testing, investigation of preform braid ability and formability at the consolidation stage.
